Numbers to Strings Implement a static String numberToString(int n ) that converts a integer n between 1 (inclusive) and one billion (exclusive) into a String. The numberToString method can cover a larger range if you wish. It should take appropriate action if the argument is out of range. For instance numberToString ( 312000789 ) should return three hundred twelve million seven hundred eighty-nine. Carefully think about how to decompose this problem. For instance, if you have a method that can handle the range 1-999, how can you use that method to create another method that handles the range 1-999999? Aim to create methods that have well-defined purposes, but which have no more than around twenty lines of code each. Exploit small private static arrays of Strings if you can. Implement a test method that provides automated testing of the numberToString method. Here, "automated" means that the test method does not require human input. Think carefully about what test cases provide good automated testing. Determine the total number of ' w 's in the words "one, two, three, .... thiry-four million nine hundred ninety-nine thousand nine hundred ninety-eight, thiry-four million nine hundred ninety-nine thousand nine hundred ninety-nine, thiry-five million." - Your program must consist of at least three classes: - one containing functions to convert positive integers to strings; - one containing test functions to test the class above; and - One to count ' w 's. - Your code should obey the following rules. - All member variables must be either private or final (both is fine). - Non-void return type functions should have minimal side-effects. Executing the same non-void function twice in a row with the same arguments should produce the same result. - Your code must conform to the follwing standards: - Class names must be capitalized. - Method names, member variables, and local variables must begin with a lower-case letter. - (exceptions) public static final variables may have all-caps names. - Methods and member variable declarations must be indented with respect to the surrounding class. - More generally, method bodies, loop bodies, and so on must be indented.
